Ubuntu Networking :: Can Disable A Specific Wireless Device

May 17, 2011

11.04 64 bit I just picked up a new high-gain usb wireless adapter that I would like to use for a while in place of the built in wireless adapter in my desktop. It is detected and works just fine. My question is this: Is there any way I can disable just the built in adapter and leave the new one active (or visa versa?) I don't want to remove the built-in one as there will be occasions that I will want to use both.

Ubuntu Networking :: Disable An On-board Wireless Device?

Nov 15, 2010

I recently bought a new nettop and installed Ubuntu 10.10 Desktop. Unfortunately the on-board wlan is kind of crap so I bought a USB Wireless stick and since that stick has a pretty recent chipset ndis was needed to get the USB stick to work as wlan1.

The issue is I want to disable the on-board wlan (wlan0). The BIOS does not offer that option so it needs to be done in the OS I guess. My question is what is the best way of doing so? I've read something about blacklisting or editing 10-wlan.rules but I am unsure what the best place is and what to put there.

This the output of ifconfig:

Quote:

eth0 Link encap:Ethernet HWaddr 00:01:2e:2b:a7:b0
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

CentOS 5 Networking :: Disable IPv6 On Specific Interfaces?

Apr 10, 2011

Now that IPv6 is becoming more and more common, I found the need to disable IPv6 on some interfaces but have it enabled on other. I found that /proc/sys/net/ipv6/conf/*/disable_ipv6 does exactly that. I am now wondering if anybody knows, why are networking scripts so counterintuitive. /etc/sysconfig/network has an option:

NETWORKING_IPV6=yes

All this option does is disable some ipv6 services (dhcpv6...), it does not disable IPv6 in whole (as one would assume...that's why you had to disable it with module parameters). Searching for more IP6 related config option, one can find that /etc/sysconfig/network-scripts/ifcfg-* scripts can contain:

IPV6INIT=yes

Again, this option does not disable IPv6 protocol on the interface, it just skips running ifup-ipv6/ifdown-ipv6 scripts. I added a /sbin/ifup-pre-local. Now, this script runs before ethX entries are created (other scripts run when it's already too late) in /proc directory, so it modifies default values which are then used after those entries are created:

#!/bin/bash
#
[ -f "/etc/sysconfig/network-scripts/$1" ] && . /etc/sysconfig/network-scripts/$1

Ubuntu Networking :: NetworkManager Tries To Connect To Wrong Device / Get To A Specific?

Oct 15, 2010

I have a ZTE 3G USB modem (MF645).
When I plug it, 5 devices appear: /dev/ttyUSB[0-4]. The modem device is /dev/ttyUSB2, and I can successfully connect wvdial on it.
NetworkManager detects the modem, however, it tries to connect to /dev/ttyUSB1 instead, and fails.

How does NM decides which device to connect to?
Is it possible to instruct it to connect to a specific device?

Ubuntu Networking :: Wireless Won't Connect In Specific Cases?

Jan 6, 2011

Most of the time my wireless works very well, connecting lightning-fast on boot with AC power. However here are two problems that I have noticed to-date: 1. Wireless will not connect if I boot on battery power. It won't connect even if I plug in the AC cable and do a reboot. Only solution is to reset the router (unplug power cable, wait, plug power cable). 2. Wireless will not connect after a Suspend, whether battery power or AC. Again, only solution is to reset the router. Another computer, running Windows XP, do not have connection problems (yes, wireless). It is quite strange, maybe some power management settings are interfering with networking? I have both laptop-mode-tools and pm-utils (re-rolled) installed.

Ubuntu Networking :: HP Pavilion Wireless Enable/Disable Button / "Wireless Disabled By Hardware Switch"?

May 11, 2011

I've had a host of problems since upgrading to 11.04 Natty Narwhal, so let's deal with these 1 at a time.

I've got a Hewlett-Packard Pavilion G60 laptop. Next to the power button is a handy wireless on/off button. This has always worked well with previous editions (9.04,through 10.10). first press toggles the wireless off, second press toggles it on.

Not so in 11.04. The toggle off works great, first time. But, it will not toggle back on. Not after any number of tries, not after restarting, not after booting into other OS's (9.10 and Vista) re-enabling it there and then booting back into Narwhal. to further complicate the issue, this feature bypass the network manager, so toggling the wireless off by the switch leaves me showing no wireless adapter in the network manager. I also restarted, switched from Unity to a Gnome session, but the issue still persists.

As my only network options are wireless, this has become a substantial inconvenience.
----
EDIT: so the network util is actually saying "wireless disabled by hardware switch". Also noticed it I enable it in 9.10, reboot to 11.04 (where I inevitably fail to re-enable it), then reboot into 9.10, it will initially be disabled. The key difference is in 9.10 I have the ability to enable wifi using the hardware button. It seems that 11.04 is remembering that wireless is disabled between boots. Is there a place it might be storing this value? If so, I may be able simply to set the value as enabled, since toggling that silly button isn't working.
-----
EDIT 2:
found this thread:"Wireless disabled by hardware switch" bug? - Natty
seems to be a similar issue. I'll be following how that one develops, too.

Ubuntu Networking :: Must Disable Then Enable Networking For Wireless?

Jan 29, 2011

My wireless can connect to my router without a problem, but in order to do so (after boot) I must first disable networking in the Notification Area and then re-enable it. I don't mind it too much, but when other people use my computer, it's made painfully obvious to me, that this was never an issue with Windows 7 (as much as I despise MS).

Ubuntu Networking :: How To Permanently Disable Wireless

Feb 14, 2010

I don't use wireless on my desktop so i would like it permanently disabled...each time i boot up it's back and receving up to 80mb of data from an unknown connection via wireless (i dont use wireless) so, to avoid any weird connections to my neighboors house or some kid hacking the neighborhood driving by with a wireless router in his truck i'd like to permanently turn off wireless. this is kind of funny because i had a hard time getting wireless to work on my laptop, but this is my desktop where i do not want it. i looked it up and your forum back in 2007 said to type in iwconfig in the shell then get the nickname of the wireless card then to black list the wireless card. i did this but it didn't work, so what do i do now? i have ubuntu 9.10

Ubuntu Networking :: 9.10 - Disable PRO / Wireless 2915ABG (Thinkpad X41)

Feb 19, 2010

I use this Thinkpad mostly for work while traveling, and wireless connectivity is not a big issue for me. Battery life is a big issue, however. I've just converted from Mandriva. With that, I was able to disable the wireless adapter so that it did nothing at all on boot - and only started on my instruction. This made a dramatic difference to battery life! How to achieve this in Ubuntu? The file attached gives all the info about my wireless set-up as it stands.

I have loaded ndiswrapper and managed to get my D-Link usb dongle working (this is wireless N) but I need to disable my laptops built in rtl8187B wireless (they both connect at log on).

In Windows I just turn of the wireless switch but in Ubuntu this disables all wireless. I think I have to black list the rtl8178b driver.

Ubuntu Networking :: Disable Media Sensing On Wireless?

Mar 20, 2011

I am doing some experiments comparing the performance of wireless under 3 different cases:

(i) without media sensing (carrier sensing).
(ii) with media sensing but no RTS/CTS
(iii) with media sensing and RTS/CTS

I know RTS/CTS can be controlled by iwconfig interface rts {N|auto|fixed|off}

However, what about media sensing? Can it be disabled? If yes, how?

Ubuntu Networking :: Disable On-board Wireless At Boot?

May 16, 2011

I have an issue with my on-board wireless card (powers down after about 5 minutes) so I'm stuck with a USB card. I don't use the on-board card and it causes the system to intermittently hang if it's powered on (once I run ifconfig wlan0 down, the system runs fine). Is there a way to power down the interface (or better yet prevent it from powering on) at boot?

Ubuntu Networking :: Disable Prompt For PUK / PIN For Broadband Wireless At Startup?

Jan 13, 2011

I've looked quite a bit, but didn't find an answer.

I have a Thinkpad x61s which comes with a "Sierra Wireless Mini Card module".

When I start up my computer, I get prompted for a PUK / PIN.

"Unlocking SIM PUK required" (sorry, this is a direct translation of the French, might not be the exact same words in English)
With three fields to fill:
Code PUK
New PIN Code
Reenter new PIN Code.

I don't have a card in my computer, and broadband mobile is not activated in networkmanager.

Does anyone have an idea how I can disable this prompt (I don't intend to put in a SIM card before some time).

Ubuntu Networking :: Wireless Device Not Detected In 9.10?

Jan 9, 2010

I have freshly installed ubuntu 9.10 and moreover i am completely a newbie to Linux. The problem now i am facing is, i am not able to configure my wireless router. I tried finding drivers for it in System->administration->hardware drivers. But it showed me none. Then i checked out one of the threads in this forum and came across the 'lspci -nn' cmd. This gave me the info abt my wireless network controller and it was : 'Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)'.

Ubuntu Networking :: Wireless Device Not Ready?

Sep 6, 2010

I've tried to install Linux systems have been failures. Trying to make this work, trying to get on the right wagon, and it's frustrating as all get-out.

Installed netbook remix onto a HP Mini 1000 (1116NR?) and everything seems to be working alright, except no wireless networking. I tried a couple of things and now it shows "device not ready" instead of "disabled", so I figure I'm getting somewhere.

The device is:

Broadcom Corporation BCM4312 802.11b/g (rev 01)

I want in. This is my 3rd try over the years of running Linux and I always hit snags like this that I can't fix because I've never gotten to play with it enough to learn what I'm doing and generally don't have a 2nd computer like I do right now.

Ubuntu Networking :: Cannot Use Internal Wireless Device

Jul 10, 2011

It's been ages since I've been on here I've been messing around with BackTrack. I've come back to Ubuntu but seem to be having some problems getting my wireless network thingy working. Here are the specs of my system. Any advice on fixing this would be very very apprciated.

02:06.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller (rev 01)
02:08.0 Ethernet controller: Intel Corporation 82562ET/EZ/GT/GZ - PRO/100 VE (LOM) Ethernet Controller Mobile (rev 01)
10:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

On another note I'm trying to run debain I've got no startx on there or anything like that it's feeling very basic atm. I want to keep startx outta there but I can't connect to the Internet and run apt-get install to grab handy things.

I'm hoping whatever I am gonna do to solve this on Ubuntu will let me connect up to my wireless network with the internal network thingy. However if it doesn't I'm guessin I can just connect up physically to the router. Any tips on doing this from the command line?
